    Defoamer XS-02 CAS 9005-67-8

    Defoamer XS-02, chemically identified under CAS 9005-67-8 as Polysorbate 60 (Polyoxyethylene Sorbitan Monostearate), is a nonionic surfactant and process aid. While broadly known as an emulsifier, in the context of the XS-02 grade, it functions as a critical surface-active agent in industrial process control and fermentation formulations. It is designed to modify surface tension and acts as a dispersant for antifoaming actives in aqueous systems, or as a foam regulator in specific textile and biological processes. We ensure bulk supply with competitive factory pricing for industrial clients. Our inventory is managed to support customized specifications, and every shipment is accompanied by complete MSDS, TDS, COA documentation.

    Other fields: defoaming of water systems in textile, printing and dyeing, rubber, leather making, etc.

    Storage conditions

    Environmental requirements
    Store in a cool, dry, well-ventilated area, away from heat sources and ignition sources.
    Avoid direct sunlight to prevent product deterioration or evaporation caused by high temperatures.
    It is recommended to keep the storage temperature within the normal temperature range (refer to the product manual for the specific temperature range).
    Container requirements
    Store in a sealed container to prevent air and moisture from entering and causing a decline in product performance.
    Avoid using container materials that are prone to corrosion or reaction (such as certain metals or plastics)

    ‌‌Safety precautions

    Avoid contact with strong oxidizers.
    Wear protective gloves and goggles during operation to prevent skin/eye contact.

    FAQ - Technical & Supply Chain

    • Q:

      What is the chemical basis of Defoamer XS-02 (CAS 9005-67-8)?

      A: It is based on Polysorbate 60, which is created by the ethoxylation of sorbitan monostearate. While chemically hydrophilic, in the XS-02 designation, it is utilized for its ability to disperse other hydrophobic components or regulate foam stability in complex industrial broths.
    • Q:

      Is this product effective in high-temperature environments?

      A: Yes, CAS 9005-67-8 generally exhibits good thermal stability. It is often used in fiber processing and fermentation tanks where temperature control is necessary, serving to maintain the homogeneity of the process fluid.
